Summary

Multiple cross-site scripting (XSS) vulnerabilities in Novell GroupWise WebAccess 6.5x, 7.0, 7.01, 7.02x, 7.03, 7.03HP1a, and 8.0 allow remote attackers to inject arbitrary web script or HTML via the (1) User.id and (2) Library.queryText parameters to gw/webacc, and other vectors involving (3) HTML e-mail and (4) HTML attachments.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Embedding Scripts in Non-Script Elements
    This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an attacker to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote attacker to collect and interpret the output of said attack.
  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Cross-Site Scripting in Error Pages
    An attacker distributes a link (or possibly some other query structure) with a request to a third party web server that is malformed and also contains a block of exploit code in order to have the exploit become live code in the resulting error page. When the third party web server receives the crafted request and notes the error it then creates an error message that echoes the malformed message, including the exploit. Doing this converts the exploit portion of the message into to valid language elements that are executed by the viewing browser. When a victim executes the query provided by the attacker the infected error message error message is returned including the exploit code which then runs in the victim's browser. XSS can result in execution of code as well as data leakage (e.g. session cookies can be sent to the attacker). This type of attack is especially dangerous since the exploit appears to come from the third party web server, who the victim may trust and hence be more vulnerable to deception.
  • Cross-Site Scripting Using Alternate Syntax
    The attacker uses alternate forms of keywords or commands that result in the same action as the primary form but which may not be caught by filters. For example, many keywords are processed in a case insensitive manner. If the site's web filtering algorithm does not convert all tags into a consistent case before the comparison with forbidden keywords it is possible to bypass filters (e.g., incomplete black lists) by using an alternate case structure. For example, the "script" tag using the alternate forms of "Script" or "ScRiPt" may bypass filters where "script" is the only form tested. Other variants using different syntax representations are also possible as well as using pollution meta-characters or entities that are eventually ignored by the rendering engine. The attack can result in the execution of otherwise prohibited functionality.

descriptionCVE(CAN) ID: CVE-2009-0272,CVE-2009-0273,CVE-2009-0274 Novell GroupWise是一款跨平台协作软件。 Novell GroupWise的实现上存在多个安全漏洞,可导致跨站脚本执行及过程指令执行等各种安全威胁。 1. /gw/webacc中的User.id t Library.queryText的参数数据没有经过充分检查过滤就返回给了用户浏览器,可能导致跨站脚本执行攻击。 2. 某些HTML邮件和HTML附件没有经过检查过滤就被使用,可能在用户浏览邮件时导致跨站脚本执行。 3. 应用允许用户未经认证通过HTTP请求执行某些操作,这可能被利用来在用户访问恶意网页时执行那些操作。 4. 应用处理POST请求的方式存在问题,攻击者可能把POST请求转换为GET请求访问到某些受限信息。 5. Novell GroupWise Internet Agent (GWIA)的实现上存在缓冲区溢出漏洞,远程攻击者可能利用此漏洞在系统上执行任意指令。 Novell Groupwise 8.x Novell Groupwise 7.x Novell Groupwise 6.x 厂商补丁: Novell ------ 目前厂商已经发布了升级补丁以修复这个安全问题,请到厂商的主页下载: 1. <a href=http://www.novell.com/support/viewContent.do?externalId=7002321 target=_blank rel=external nofollow>http://www.novell.com/support/viewContent.do?externalId=7002321</a> 2. <a href=http://www.novell.com/support/viewContent.do?externalId=7002320 target=_blank rel=external nofollow>http://www.novell.com/support/viewContent.do?externalId=7002320</a> 3. <a href=http://www.novell.com/support/viewContent.do?externalId=7002319 target=_blank rel=external nofollow>http://www.novell.com/support/viewContent.do?externalId=7002319</a> 4. <a href=http://www.novell.com/support/viewContent.do?externalId=7002322 target=_blank rel=external nofollow>http://www.novell.com/support/viewContent.do?externalId=7002322</a> 5. <a href=http://www.novell.com/support/viewContent.do?externalId=7002502 target=_blank rel=external nofollow>http://www.novell.com/support/viewContent.do?externalId=7002502</a>
